Abstract
A synchromesh transmission of the type having a forward-reverse input section (18), an intermediate 4-speed constant mesh transmission (20), and a high-low output section (22). The 4-speed intermediate section has four driven gears (54, 56, 78, 80) mounted on a main shaft (24) for rotation therewith and respectively in constant mesh with four drive gears (50, 52, 70, 72) each of which can be selectively coupled to a countershaft (28) by synchronized collar-shift mechanisms (58, 68). The total shift effort required to engage the ratio of the intermediate change gear mechanisms is minimised by arranging at least three (50, 52, 70) of the drive gears to be of substantially smaller diameter than the corresponding driven gear.
